Well, I wonder how many people lost their enthusiasm for a more equal footing when they see people with absurd hash rates from companies like that. I did, it became less something that was fun as everything gets sucked their way, and the little nubs like me with single gpus basically scrape in a few coins a day.
A single GPU can rake in GeistGeld, CoiLedCoin, and GRouPcoin, maybe even i0coin, quite nicely merged-mining, and since those are just the easiest of the merged-mined coins can also have the small chances of eventually finding blocks of IXCoin, DeVCoin and NaMeCoin n too by merging the whole lot of them. Furthermore, just the BiTCoin alone will more than pay for the electricity.
(You use p2pool for the merged mining, so you get the benefits of a pool for the bitcoins, the rest you are gambling on find a block yourself solo, which is a good bet for the lower difficulty coins. One 5870 gets lots of blocks of the low difficulty coins per day. While the bitcoins pay the electircity plus also some profit too just on the bitcoins before even considering all the effectively-free altcoins.)
